Synopsis

A group of fresh faced scientists have biweekly informal discussions about evolutionary biology and palaeontology... over beer.

Episodes

  • Podcast 82 - So Like Majora's Mask; Astrobiology and Cyclicity of Extinction

    17/04/2016 Duration: 01h15min

    In this episode, we wanted to discuss large-scale astrobiological patterns and cyclicity of extinction, but instead we picked a few papers that weren't directly focused on those themes. So join us as we talk around two astrobiology papers! Meanwhile, James nearly becomes a mass extinction, Curt considers the psychological health of the hero of Hyrule, and Amanda gives her cat some tough love.

  • Podcast 81 - Niche Ontogeny; The Hero This City Deserves

    03/04/2016 Duration: 01h32min

    In this episode the gang discusses two papers about how niche breadth can change as organisms grow, with one paper looking at modern organisms and the other focusing on extinct fossil taxa. Also, James is fascinated by New York's greatest "hero", Amanda becomes "enthusiastic" in her defense of a topic, and witness the dark middle chapter of the podcast as Curt "ruins everything". We also have an in-depth discussion on what can and cannot be classified as a pie.... it's one of those podcasts. Skip to 12 minutes in if you want to start learning about science.

  • Podcast 80 - The Severity of The Sixth Mass Extinction, A Belated Birthday Fun-Time Celebration

    20/03/2016 Duration: 01h26min

    In this episode, the gang celebrates its third year of podcasting by discussing two papers that use the fossil record to determine how our current biodiversity crisis stacks up to past mass extinctions. Also, Amanda deals with abandonment, James explore New York, and Curt gives life lessons from 70s film.

  • Podcast 78 - History Repeats, Bizarre Convergence in Fossil Animals

    21/02/2016 Duration: 01h09min

    The gang discusses three papers that detail some truly unique examples of morphological convergence; from brachiopods that look like corals to bovids with dinosaurian nasal crests. Also, James designs some conspicuous Mario levels,  Amanda wins an argument that "never happened", Curt is excluded from a business venture, and everything comes back to Zardoz.

  • Podcast 77 - Old and Burny, A Discussion of Fossil Fungi

    07/02/2016 Duration: 01h15min

    In this episode, we discuss the complex relationship between fungi and earth systems processes through time, focusing on the potential role of fungi in facilitating early terrestrialization and the proposed hypothesis that fungi may (or may not) have been indirectly responsible for the Carboniferous coal swamps. Also, Amanda aggressively segues, Curt derails the conversation into navel gazing about the nature of scientific fields, and James goes on a fascinating journey from Angry to Annoyed finally ending up at Resentfully Happy.

  • Podcast 76 - In Which James and Amanda are Slightly too Inebriated to Discuss Mesozoic Fossils

    24/01/2016 Duration: 01h18min

    In this episode we discuss a grab bag of Mesozoic papers, ranging from potential dinosaur mating dances to large-eyed mosasaurs. And after a fairly sober month, Amanda and James dive headfirst into the highest alcohol content beer they have with expected disastrous results. Come and join us as Amanda tries her hand at ASMR, James uncovers a plot to destroy him, and Curt enjoys being the most sober person in the room. Also we keep talking about The Thing for some reason... References Lockley, Martin G., et al.

  • Podcast 75 - New Years Resolutions and Sponges Y'all!

    10/01/2016 Duration: 43min

    We ring in the new year by talking about new research on the evolutionary history of early animals. Also, Amanda makes some very deep cartoon cuts, James manages an emergency, and Curt makes impossible resolutions.  References: Pisani, Davide, et al.

  • Podcast 74 - Early Tetrapods Awaken

    27/12/2015 Duration: 53min

    In this episode, we discuss two papers about early tetrapods/tetrapodomorph taxa, Tiktaalik  and Ichthyostega, and what new findings suggest about their locomotion. Also, Curt makes a suspicious delivery, and James desperately tries to feed Amanda "spoilers" for the new Star Wars. EDITOR'S NOTE: While I cannot confirm that any of James's spoilers are indeed accurate, they seem highly unlikely to be true (although if they are true, then the film they suggest is AMAZING). Up goer five simple text summary: The group takes time out from a time when not much is meant to happen to talk about some animals with big arms that were some of the first animals with four legs to come on to land. In between talking about a space movie where people use guns that fire light to show how they feel about each other, the group looks at a paper looking at the back end of an animal that had before been known only from its front. This new part of the animal shows that it had very small back legs that still looked more like for use i

  • Podcast 73 - Sincere Apologies to All Ammonite Workers

    13/12/2015 Duration: 01h18min

    In this episode, we discuss two papers that describe ammonite feeding habits. Meanwhile,  Amanda gets into a boxing match, Curt is introduced to Moon Moon, and James is completely derailed by an animal.... again. Also, James invents a completely ridiculous life strategy  for ammonites (34 :30) that Curt is just drunk enough to truly appreciate.  Simple text summary The groups looks at two papers to find out what old animals with many arms and a hard house that they moved about the water in ate. The first paper studies old animals that have been looked at with a computer to see inside them and look at their teeth. The study shows that some of these many armed house carrying animals ate tiny animals that fill the water. The other paper looks at the mouths of other types of animals with arms that carry houses on them and finds that they are very different. This paper shows that several different types of animals with arms that cary houses ate different things, and that the oldest type of eating is still seen tod

  • Podcast 72 - Converging on a Topic

    29/11/2015 Duration: 01h13min

    Fresh off of GSA, the gang gets together to discuss a quick paper about the extent to which adaptation can overprint historical signal in evolution. Afterwards, James and Curt update Amanda with the highlights of GSA. Meanwhile, Curt explains quarter based economics, James hosts a quiz show, and Amanda is delighted by a paper.  "Your Call" Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0http://creativecommons.org/licenses/by/3.0/  References:  Ord, Terry J., and Thomas C.

  • Podcast 71 - GSA 2015

    15/11/2015 Duration: 03h08min

    It's that time of year again, so James and Curt bring you day by day coverage of the 2015 Geological Society of America meeting, joined by friends Brendan Anderson and Tory McCoy. So join us for an ethically compromised good time as they discuss the fascinating work of strangers, friends, and themselves. Day 1: James and Curtis Day 2: James, Curtis, and Brendan starts at 0:50.40 Day 3: James, Curtis, Brendan, and Tory starts at 2:03.22.

  • Podcast 70 - Systems Breaking Down; The End of the Ediacaran

    01/11/2015 Duration: 01h46min

    The gang discusses two papers that deal with the events that led to the extinction of the early metazoan Ediacaran fauna, as well as the extinction's philosophical ramifications for our understanding of evolution in general. Chaos runs rampant throughout this podcast as our figurative and literal systems break down through time. But somehow, life.... finds a way.... through a 4G network. Meanwhile, Amanda jumps the gun, Curt makes jokes no one can understand, James "wins" again, and everyone slowly succumbs to chaos and madness. If you're just joining us for the first time, I'm so very... very sorry.    References: Darroch, Simon AF, et al. "Biotic replacement and mass extinction of the Ediacara biota." Proc. R. Soc. B.

  • Podcast 69 - Tasty Kosher Food

    18/10/2015 Duration: 01h18min

    The gang finally just does what comes naturally and discusses two papers about food. Specifically, one paper on why things aren't tasty and another answering the vital question "what foods in the past would be kosher" (the answer might just surprise you). Meanwhile, Amanda finds her spirit animal, James details our terrifying corporate future, and Curt wants to play a game. TRIGGER WARNING: Mild joking reference to sexual-violence and mascots in the first two minutes. TRIGGER WARNING: We talk about eating meat throughout.  Up-goer five simple-speak text: The group talks about two papers that look at food and which animals make good food. The first paper looks at the babies of small animals that have pretty things that let them fly. They find out that the babies that ate things with leaves that made bad food also made bad food themselves and would be ignored by other small animals that tried to eat them. The other paper works out whether animals in the past would have been good food for people that have very f

  • Podcast 68 - Plonts

    04/10/2015 Duration: 01h28min

    The gang discusses two papers about the evolutionary placement of some Cretaceous flowering plants (angiosperms). Meanwhile, Amanda finds her alter ego,  James goes very old school with his jokes, and Curt really doesn't want to talk about the next paper.   References Friis, Else Marie, et al.

  • Podcast 67 - Stratigraphic Bias

    20/09/2015 Duration: 01h35min

    The gang discusses two papers that detail how the stratigraphic record affects our understanding of the fossil record.  Meanwhile, Amanda gets very enthusiastic, James burns straw men,  and Curt isn't sorry.   References Benton, Michael J.

  • Podcast 66 - Penguin Death Land

    06/09/2015 Duration: 01h14min

    In this episode the gang tries to have a discussion about the fossil preservation of birds. Instead they get completely sidetracked imagining the penguin apocalypse. Meanwhile, Amanda slowly goes crazy, James keeps hearing things, and Curt delights in a mispronunciation.   "Up goer five" text summary This time the group looks at papers about how animals that have bits that mean they can fly break down when they are dead. The first paper looks at what happens to animals that have bits that mean they can fly when their bodies are left in bad water. These studies are used to see how long animals that could fly were dead before they were covered by stuff in old places where lots of dead things are found in the same place. The study shows that there are fewer types of animals that could fly in these old places where lots of dead things are found in the same place than we would expect. The second paper uses a computer to find out whether we should expect to find all the types of animals that could fly in these old

  • Podcast 65 - SEX!

    23/08/2015 Duration: 01h23min

    The gang goes broad and tackles two papers that deal with evidence of sex and reproduction in the fossil record. Meanwhile, Amanda goes method, James invents a new scientific term, and Curt is haunted by one terrible joke that will not die. "Hyperfun" Kevin MacLeod (incompetech.com) Licensed under Creative Commons: By Attribution 3.0http://creativecommons.org/licenses/by/3.0/ "Up goer five" text summary Today the group talks about fucking. Yes, fuck is one of the ten hundred most used words, while better and less bad words for fucking are not. You think what that means about people. Just think about it. The first paper is looking at the oldest pictures of stuff that comes out of a man after he has had a fuck. This fuck water is from a small animal with no hard parts and so we usually do not know that the animal was there. However, the fuck water is different for different types of small animal, and so we can see what small animals with no hard parts were there without seeing the actual animals. The fuck water

  • Podcast 64 - Walk Before You Crawl; Convergence in Dinosaur Gait

    09/08/2015 Duration: 01h03min

    The gang discusses two papers about the evolution of quadrupedal lifestyle in ornithischian dinosaurs. Also, James discusses the joys of being a squid, Curt details the ideal political tag-team match,  and Amanda dreams of HD belts. "Up goer five" text summary The group talks about big angry animals without hair - again. This time they look at two studies that look at how one group of big angry animals with no hair went from walking on two feet to walking on four. Three different bands of friends in the group have gone back to walking on four feet by themselves. The first paper looks at figuring out the soft parts to work out how they walked and finds that each of these three types of big angry animals without hair walk in different ways, even though they all walk on four feet. The second paper looks at why these three types of animal have gone back to walking on four feet by seeing where they got big and whether it would make them fall forwards or back. This was studied by sticking heavy bits of animals with

  • Podcast 63 - Meaty; The Evolution of Hypercarnivory

    26/07/2015 Duration: 01h32min

    The gang discusses two papers about the evolution (and loss) of hypercarnivory in mammals. Meanwhile, Amanda shares more equine history, Curt does his best to kill a trend, and James goes "nuclear". Please bear with us.... BEAR.
